  • Where to put compiled FFmpeg files ?

    25 octobre 2019, par Spikekyn

    So I’m attempting to build an android app that uses the LUT3D part of the FFMpeg libraries to edit video. I’m pretty new to this so I’m having difficulty understanding how to get it to function in Android Studio.

    I currently am using WritingMinds ffmpeg-android-java to try and get it to work. But I’m pretty lost as what to even do with the files. Most of the stuff I’ve found has been pretty old so I’m not sure if it’s still valid. Any help would be appreciated.

  • Why after rendering with ffmpeg, file size did not decrease ?

    15 avril 2021, par ptrra

    PROBLEM : After rendering a certain video with ffmpeg file size increased from 4GB to 6GB.
    
ORIGINAL VIDEO : EE1.mkv
    
FFMPEG COMMAND : ffmpeg -i EE1.mkv -c:a copy -c:v libx264 -crf 23 -preset medium -profile:v high out.mp4
    
QUESTIONS : Why did the file size increase ? What am I doing wrong ?

    


     !DETAILS !
    
After a few years I made about 30 gaming videos (130GB) and with the current covid-19 situation I started recording my online classes (about 40 videos or 150GB). Now because I'm lacking space on my 1TB external HDD I started getting into ffmpeg. Before I was only using obs-studio and not good parameters for recording.

    


    I was using CBR mode for recording, either 5000KB or 15000KB bit rate with varying x264 presets and profiles because I was also experimenting with them. Usually superfast preset with high profile. So I wanted to convert all those videos with ffmpeg using CRF 23, medium preset and high profile. A note that when I'm recording with obs-studio it's set to record in matroska format (.mkv).

    


    When I was rendering my online classes videos with these settings I managed to achieve 10x better compression with the same quality. And when rendering my gaming videos I managed to achieve up to 3x better compression with the same quality. However there is this one video that when rendered with the same parameters the file size increases.

    


    The EE1.mkv should be recorded with CBR 15000KB bit rate, with superfast preset and high profile. Also the game that is recorded in this video is Empire Earth which needs around 8000KB for it to look good. Everything more than 8000KB is not needed.

    


    Thank you all for your help.
